problem with my laptop screen
Hello,
I bought my laptop about 3 months ago. About a week or so, I have noticed that on the top left corner there is a some sort of flashing light. I have no idea why or how to fix it and it appears only at the top left corner of the screen. I updated all the drivers but it didn't help. I don't know what else I can do. Maybe someone can help me to figure out what the problem is and how to fix it? I uploaded a short video to show you what the problem is. I hope you can see it as clearly as I can see it. Please help me.
Thanks.

I see nothing wrong in that video? Do you see the issue when running the LCD BIST (Built In Self Test) ?

Because you did NOT see the issue when running the LCD BIST, then we know that the LCD, LCD cabling, and GPU are OK. This means the fault is either the operating system GPU driver, or the something else in the operating system. But not a hardware issue.
